On the devboard it's actually normally a capacitor mounted,
although there is an alternative footprint to fit a battery as well.
However, to charge the capacitor you need to enable the "tripplecharger"
in the rtc chip.
to enable it and put that in the inittab or an init script.

You probably need to change the /dev/console link as well.
